(A)   (1)   The Building Commissioner shall review all building permit applications for new construction or substantial improvements to determine whether a proposed building site will be reasonably safe from flooding.
      (2)   If a proposed building site is in a location that has a flood hazard, any proposed new construction or substantial improvement must be designed and anchored to prevent flotation, collapse or lateral movement of the structure; use construction materials and utility equipment that are resistant to flood damage; and use construction methods and practices that will minimize flood damage.
   (B)   The Building Commissioner shall review subdivision proposals and other new developments to assume that all such proposals are consistent with the need to minimize flood damage; all public utilities and facilities, such as sewer, gas, electrical and water systems are located, elevated and constructed to minimize or eliminate flood damage; and adequate drainage is provided so as to reduce exposure to flood hazards.
   (C)   The Building Commissioner shall require new or replacement water supply systems or sanitary sewage systems to be designed to minimize or eliminate infiltration of floodwaters into the systems and discharges from the systems into floodwaters, and require on-site water disposal systems to be located so as to avoid impairment of them or contamination from them during flooding.
